Uncaught (in promise): Error: Supplied data is not a JPEG

[NikhilRadadiya]

Thank you for submitting an issue to jsPDF. Please read carefully.

Are you using the latest version of jsPDF?
Yes, I'm using 1.3.2
Have you tried using jspdf.debug.js?
Yes
Steps to reproduce
As I'm having problem with images, I can't reproduce it on jsbin

These are the libraries i'm using

       <script src="assets/js/jspdf/dist/html2canvas.js"></script>
       <script src="assets/js/jspdf/plugins/addimage.js"></script>
       <script type="text/javascript">
       function createPdf(){
           const elementToPrint = document.getElementById('main');
           console.log(elementToPrint);
           const pdf = new jsPDF('p', 'pt', 'a4');
            pdf.addHTML(elementToPrint, () => {
              pdf.save('t_web.pdf');
            });
         }
</script>```

**HTML**

```<div class="main" #main id="main">
      <section id="intro" class="intro-section">
         <div class="banner_wapper">
            <div class="banner_container">
               <div class="banner_info">
                  <div class="container">
                     <div class="row">
                        <div class="col-md-12">
                           <div class="banner_t_detail">
                              <h1><span>Flamingo - </span>Toyota Diwali 2017 Group</h1>
                              <div class="banner_t_detail_btm">
                                 <p> 6 Nights 7 Days - Thailand</p>
                                 <span>Inquiry #123456789 12th May, 2017  -  Quotation #123456789 16th May, 2017</span>
                                 <span>2 Nights Bangkok, 1 Night Pattaya, 2 Nights Phuket, 1 Night Krabi</span>
                              </div>
                           </div>
                        </div>
                     </div>
                  </div>
               </div>
            </div>
         </div>
      </section>```

```.banner_container``` contains image as background image
(This is just a small part from original html, original html contains more images)

**What I expected**
I expected a pdf file containing output like html is producing

Please help me fix it

Do you use JPEG2000?

[NikhilRadadiya]

@arasabbasi No, Im not using that.

[Uzlopak]

In my opinion the jpg support in jspdf is very poorly implemented. You should check the validity of the used jpegs.

[NikhilRadadiya]

@arasabbasi anyways I've stopped using jspdf, instead I'm using pdfmake now.
Thanks for your answer. but I would have love to see a solution here

[Uzlopak]

I added filetype recognition for addimage. Probably with next version of jspdf you could try it again and tell us what it shows then..

I close here for now. On request reopening the issue.
